Oxide IonGallium Oxide is a highly insoluble thermally stable Gallium source suitable for glass, optic and ceramic applications. The precipitation of the hydrated form of gallium oxide is caused by the neutralization of acidic or basic gallium salt solution. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive findingHigh Purity (99.999%) Gallium Oxide (Ga2O3) Powder application in the cathode of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Metal oxide compounds are basicanhydrides and can therefore react with acids and with strong reducing agents in redox reactions. Gallium Oxide is also available in pellets, pieces, powder sputtering targets, tablets, and nanopowder (from American Elements' nanoscale production facilities). See Nanotechnology for more nanotechnology applications information. Gallium Oxide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Additional technical, research and safety (MSDS) information is available.

Gallium (Ga) atomic and molecular weight, atomic number and elemental symbolGallium (atomic symbol: Ga, atomic number: 31) is a Block P, Group 13, Period 4 element with an atomic weight of 69.723.The number of electrons in each of Gallium's shells is 2, 8, 18, 3 and its electron configuration is [Ar] 3d10 4s2 4p1. The gallium atom has a radius of 122.1 pm and a Van der Waals radius of 187 pm. Gallium Bohr ModelGallium was predicted by Dmitri Mendeleev in 1871. It was first discovered and isolated by Lecoq de Boisbaudran in 1875. In its elemental form, gallium has a silvery appearance. Elemental GalliumGallium is one of three elements that occur naturally as a liquid at room temperature, the other two being mercury and cesium. Gallium does not exist as a free element in nature and is sourced commercially from bauxite and sphalerite. Currently, gallium is used in semiconductor materials for microelectronics and optics. The element name originates from the Latin word 'Gallia', the old name of France, and the word 'Gallus,' meaning rooster.
